HYPERTROPHIC CARDIOMYOPATHY


Hypertrophic cardiomyopathy (also known as HCM, IHSS, hypertrophic obstructive cardiomyopathy) is an illness affecting the heart muscle. It interferes with the heart’s ability to pump blood. Sometimes it also changes the heart’s natural rhythm, which leads to irregular heartbeats (arrhythmias). One type of cardiomyopathy, hypertrophic cardiomyopathy, occurs when the heart’s muscle fi bers grow abnormally. Heart walls thicken, especially in the left ventricle (the main pumping chamber). The left ventricle becomes smaller inside, the heart cannot rest completely between beats, and the ventricle pumps less blood out of the heart. People are at risk for fainting (syncope), chest pain (angina), diffi culty breathing
(dyspnea), and sudden death. Hypertrophic cardiomyopathy affects people of all ages, including children. It can cause sudden death even in children and young adults.


cause
Hypertrophic cardiomyopathy is usually inherited (passed on from parents). Once someone is diagnosed, all immediate family members should be tested. The cause in some elderly people
may also involve long-standing untreated high blood pressure (hypertension).


symptom
Symptoms include shortness of breath when walking, performing household tasks, or with any exertion; chest pain; fainting after exercising; and irregular or very rapid heartbeat. Some people have no symptoms, and sudden cardiac arrest may often be the fi rst sign of this disorder.

diagnosis
The doctor will check the medical history and do a physical examination. Tests for diagnosis include chest x-rays, electrocardiogram (ECG), and echocardiography (ultrasound of the heart). Other tests, such as 24-hour recording of the heartbeat and blood tests may also be done. Genetic testing using a blood test and magnetic resonance imaging (MRI) of the heart may also be done.

treatment

Treatment is aimed at controlling symptoms and slowing the disease progress by reducing excessive contractions of the ventricle. Symptoms of heart failure and arrhythmias are also
treated. Drugs are usually prescribed to regulate the heart rate and strength of contractions. These drugs include beta-blockers (e.g., propranolol) and calcium channel blockers (e.g., verapamil). A pacemaker/defi brillator/cardioverter is an option to control the heartbeat. It is a small device that is put into the body during surgery. Surgery may also be done to remove part
of the abnormal muscle (septal myectomy) and reduce the blockage of blood fl ow. Destruction of a portion of the wall between ventricles (alcohol septal ablation) may also be done. Heart transplantation is possible for people who don’t respond to other treatments.


Things to do

Do take medicine as prescribed by your doctor.

Do tell your doctor if your symptoms get worse or don’t
improve with treatment.


Do remember that family members should be checked
for this disorder.


Do call your doctor if you have new or worsening chest
pain, shortness of breath, swelling in the legs, or fainting.




don't do

DON’T change your exercise program without telling
your doctor fi rst.


DON’T take over-the-counter drugs, foods, or herbal
supplements before checking with your doctor because
they may react with your heart medicine.

DON’T smoke.

DON’T drink alcohol.

DON’T use diuretics (water pills).
